TECHNICAL FIELD

The present disclosure in general relates to a system for processing distributed data files and a method thereof.

BACKGROUND

In a communication network, with the explosion in data, there is a need for data warehouses which can handle very large files. Data in such data warehouses is stored in a distributed manner. Such distributed data files are consumed by the data warehouse and are validated, transformed, processed and loaded/stored in the data warehouse. Data is pushed to the warehouses by multiple sources and most often, the data warehouse does not have any control on the source of the data being consumed. With the growth in the volume and size of data, the computer systems become inefficient to process the incoming data.

The speed with which the new data sets are being generated, there is a high likelihood that the data sources may change, or the format of the data file may change. Existing files may also get modified or their formats may be changed. Further, it may be possible that position of attribute(s) in the data file changes or new attributes get added to the data files over a period. The changes in the upstream systems breaks the data warehouse systems, causing a significant downtime to address/configure and/or support new set of files or file formats or new set of rules.

Some embodiments of the present disclosure, illustrating all its features, will now be discussed in detail. The words “receiving”, “generating”, “executing”, “transforming”, “determining”, “transmitting” and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items. It must also be noted that as used herein and in the appended claims, the singular forms “a”, “an” and “the” include plural references unless the context clearly dictates otherwise. Although any systems and methods similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present disclosure, the exemplary, systems and methods for processing distributed data files are now described. The disclosed embodiments of the system and method for processing distributed data files are merely exemplary of the disclosure, which may be embodied in various forms.

Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. However, one of ordinary skill in the art will readily recognize that the present disclosure for processing distributed data files is not intended to be limited to the embodiments illustrated but is to be accorded the widest scope consistent with the principles and features described herein.

In a communication network, the speed with which the new data sets are being generated, there is a high likelihood that the data sources may change, or the format of the data file may change. Existing files may also get modified or their formats may be changed. Further, it may be possible that position of attribute(s) in the data file changes or new attributes get added to the data files over a period. The changes in the upstream systems breaks the data warehouse systems, causing a significant downtime to address/configure and/or support new set of files or file formats or new set of rules. Because of this, the system becomes inefficient.

The present subject matter relates to processing distributed data files. In one embodiment, a system may comprise a processor and a memory coupled with the processor. The processor may be configured to execute instructions stored in the memory. The processor may execute instructions to receive a set of instructions from a primary device, wherein the set of instructions may comprise verification rules, validators, primary transformers and structured query transformers. The processor may further execute instructions to generate processed data files by processing the distributed data files based on one or more characteristics of the distributed data files. The distributed data files may be processed by performing at least one of the following steps. The distributed data files may be processed by executing at least one of the verification rules, the validators and/or the primary transformers on the distributed data files; or by transforming the distributed data files by executing the structured query transformers on the distributed data files. The execution of the structured query transformers may comprise steps of generating a dependency graph based upon dependencies between the structured query transformers; and determining a sequence of execution of the structured query transformers based upon the dependency graph. The processor may further execute instructions to transfer the processed data files to a data warehouse.

The system for processing distributed data files is advantageous because the system may be configured to decouple the processing of the distributed data files from the data warehouse. The system may be configured to verify, validate and transform the distributed data files to a format that can be readily consumed by the data warehouse by retaining existing implementation of the system. The system is advantageous because it handles any change in upstream data sources, format changes and attribute changes without any downtime for the data processing. Further, the system handles structured query transformations to be applied on the distributed data files without any modification/changes to the existing implementation of the system. Any new data sources or distributed data files may be added to the system by just providing a new configuration file or modifying an existing configuration file. The new transformers, validators, verification rules to be supported by the system may be specified by adding new methods and providing the methods to the system through a software library. The system may comprise a core processing engine. The core processing engine may not change for supporting any new set of verification rules, validators or transformers.

In one aspect, the user may access the I/O interface 204 of the system 102 for obtaining information, providing input information or configuring the system 102.

In one embodiment, the data receiving module 210 may receive a set of instructions from a primary device 108. The set of instructions may comprise verification rules, validators, primary transformers or structured query transformers. The data receiving module 210 may further receive distributed data files from the user device 104. The distributed data files may be of any size although the system is designed to handled very large size distributed files. Each of the distributed data files may comprise various attributes.

In one aspect, the system defines a set of basic validators and transformers called base modules. The base modules define basic attributes and behaviour of validators and transformers. Any validators and transformers whose behaviour is not covered by the existing validators/transformers may create a new set of validators or transformers by extending these core validators/transformers and provide their own implementation of the required behaviour. This makes the system flexible. Further, any new validators or transformers thus implemented may be provided to the system as a shared library that may be loaded by the system at run time or as a static library which can be bound to the software system at compile/linking time. The basic framework of the system may not need to change to support new validators/transformers. It provides an enormous flexibility to the system. The validators and transformers may be specified by the primary device 108. The system may be built with a set of validators and transformers. There may be multiple primary devices for providing the structured query transformers to be executed by the system

In one embodiment, new rules not supported by the system may be added to the existing system without changing the existing implementation of the system 102. The new rules may be required to extend the existing validation or transformation rules or the base modules. These new rules may be compiled into an external library and provided to the system 102, which can load these new set of rules. The system 102 may not need to be re-implemented to support the new set of validators or transformers.

Further, the primary device 108 may be an external configuration file which may be generated by text editor or by any other system. The configuration file may be used to provide instructions to the system about the different rules to be executed for processing the distributed data file and also configure the rules by providing the necessary attributes for those rules. The external configuration file may comprise of three segments such as a first segment, a second segment and a third segment. The first segment may be configured to store name, location, format of the input data files, format of the output distributed data files. The second segment may be configured to provide verification rules for the distributed data files. The third segment may be configured to provide validators and, the primary transformers. The structured query transformers may be provided in a separate configuration file(s)

In one embodiment, the distributed data files may be of very large size and thus may require multiple machines to process the large distributed data files. In such case, the primary device 108 may be read by the main processing system and instances of the validators and transformers created and these may be transferred to each of the machines responsible for processing different chunks of the distributed data file, so that all the machines may process the different chunks of the same distributed data files using the same set of instructions.

The data processing module 212 may generate processed data files by processing distributed data files based on one or more characteristics of the distributed data files. The one or more characteristics of the distributed data files may comprise of format of the distributed data files, schema of the distributed data file, verification and validation and transformation rules. The processed data file may be stored in the data warehouse in a format specified by the primary device 108. The format may be a text file, comma separated file, tab separated file, parquet file, tar file, zipped file and the like. The data processing module 212 may process the distributed data files by performing at least one of the following steps.

Step 1: The execution module 214 may execute one of the verification rules, the validators and the primary transformers on the distributed data files, and

Step 2: The transformation module 216 may transform the distributed data files by executing the structured query transformers on the distributed data files.

In one embodiment, the primary transformers may be applied to the attributes of the distributed data files and may be configured to transform the distributed data files to a predefined format. The predefined format may comprise csv, tsv, parquet, avro, orc, etc. The predefined format may be consumable by a data warehouse.

In an exemplary embodiment, the primary transformer “Multiply” may be applied to “Multiply an attribute value by predefined constant number” which may convert value of the attribute to required value by multiplying the value with the predefined quantity.

In another exemplary embodiment, the primary transformer “Date” may be applied to convert a date attribute into another date format like a mm-dd-yyyy (month-date-year) to another format like dd-mm-yyyy (date-month-year). There may be plurality of primary transformers such as but are not limited to (a) converting an attribute to a different format for example stripping off decimals from an attribute that may signify price of a commodity, (b) date transformer which may transform dates from say dd-MM-yyyy to MMM-dd-yyyy format, (c) transformer to populate null values with a default value, (d) column joiner transformer which may join two columns like joining first name and last name of a person to provide full name, (e) column splitter transformer which may split a column into multiple columns like splitting an address into address, zipcode, country, etc.

In an exemplary embodiment, various primary transformers may be shown in the table below:

Attribute S.No Rule Type Explanation 1 Date Transformer Double Converts the date time field based on the date format 2 AttributeSplitter Text Split the attribute on the basis of a rule like a comma, space, pattern etc 3. Multiplier Float, Convert the column by integer multiplying with a constant specified 4. NullValuesRemover Float, Remove empty attribute values Integer, and replace them by 0 for text attributes of type float or integer and by “” in case of text 5. Extractor Text Extract a pattern from the attribute value 6. ColumnJoiner Text Join two columns into a new column

In one embodiment, the verification rules may comprise global rules which may be applied on the distributed data files. The rules may be such as but are not limited to: a) number of missing attributes allowed rule, which specifies constraints on the number of missing attributes allowed for each sample/row of data in a file, which may instruct the system 102 that if the number of missing attributes for each sample of data in the distributed data file exceeds the provided threshold value, the sample of the data to be considered as defective, b) duplicate samples to be allowed or filtered etc. If in case, the verification rules are breached, the data samples may be filtered and stored in an error file having specific name and location provided by the primary device 108

The various validators may be such as but are not limited to (a) whether the field is mandatory or not (NULL value check), (b) any constraint on the length of an alphanumeric field, (c) numeric attribute validation, (d) min value check, (e) the max value check, (f) pattern check i.e., if a field/attribute is a zip code, whether the zip code is of specific format like xxxx or a phone number is of a specific format like xxx-xxx-xxxx etc, (g) referential validation i.e, check whether value in one field should be greater than, equal to or less than the value in another field, lookup check i.e., (h) lookup validator i.e, check whether the attributes are valid values by looking up into a reference store for example if the attribute should contain a country, check whether the value of the attribute is a valid country etc.

In an exemplary embodiment, various validator rules may be shown in the table below:

S.No Validators/rules Attribute Type Explanation 1 Mandatory NA If set to yes, and attribute is not present, drop the record 2. Length Text Maximum length of a text attribute allowed. 3 Max Float, integer Maximum value of the attribute allowed 4. Min Float, Integer Minimum value allowed. Records with attribute value lower than specified will be marked error records and filtered 5 Negative Float, integer Whether the attribute can be negative or not 6. Format Text The attribute format if any to be enforced. Like zip code xxxx, phone number xxx-xxx-xxxx 7. Lookup Any Look up into the system 102 for the validity of the value in this field. For example, if the data is a state, whether the value specified is valid state.

In one embodiment, the system 102 may be developed and designed with a set of verification rules, validators and transformers to be supported by the system 102. Over a period of time, the system 102 may be required to add new validators and transformers. The system 102 may dynamically add or replace the verification rules, the validators, the primary transformers and the structured query transformers to the primary device by retaining an existing implementation of the system 102.

In an exemplary embodiment, the system 102 has to transform US$ to Euros, the new set of instructions i.e. verification rules, the validators, the primary transformers and/or the structured query transformers may be added to the primary device by retaining an existing implementation of the system 102.

In one embodiment, the set of instructions stored in the primary device 108 may be read by the system, deserialized and converted to a set of validators and transformers and transferred to the system 102 responsible for executing the instructions while processing the distributed data files. In one aspect, the set of instruction may be reconverted from the deserialized format to a serialized format to be distributed across the network to different such systems involved. The transformation module 216 may execute the structured query transformers on the distributed data files by performing following steps.

Step 1: The transformation module 216 may generate a dependency graph based upon dependencies between the structured query transformers.

Step 2: The transformation module 216 may determine a sequence of execution of the structured query transformers based upon the dependency graph. The sequence of execution of the structured query transformers may be established by resolving unresolved dependencies by looking up to the structure queries. The transformation module may identify missing dependencies and generate errors if there are such missing dependencies.

In one embodiment, the system 102 may maintain a list of the files or tables created in memory 206. It may look up to the memory 206 to find out all the tables in dependency list. For example, let us assume a query “QUERY1”, which requires input “table/file” A and B. Let us assume that the output of this query be given a logical name as “C”. Another query “QUERY2” may require input table/file A and C and may generate an output table/file named “D”. The system 102 may create a dependency list which tells the computer system that for generating data to be stored as “D”, it needs data/table named “A” and “C” and for generating “C” it needs data/table “A” and “B”. So, the order in which the processing needs to be performed may be to execute QUERY1 first and then QUERY2 even if these structured queries are specified in an unordered manner in the primary device 108.

In one embodiment, the structured query transformers may be received as a key and value pairs. The key may indicate a symbolic name for data generated after transformation performed using structured queries. Further, the value pairs may indicate the structured queries to be applied for the transformation.

In one embodiment, the dependencies may be extracted from the structure queries provided by user device 104 via the primary device 108.

In one embodiment, the system 102 may be configured to generate intermediate temporary tables during execution of the transformations using the structure queries. The temporary tables may be removed after the processing is completed. The temporary tables may be given logical names based upon the type of data in the temporary tables. In one aspect, the temporary tables/files may be removed after execution of the queries.

The data transmission module 218 may transmit the processed data files to the data warehouse.

Referring now to FIG. 3 , a method 300 for processing distributed data files is disclosed, in accordance with an embodiment of the present subject matter. The method 300 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, functions, and the like, that perform particular functions or implement particular abstract data types.
